This study introduces an image processing algorithm for interpreting American Sign Language (ASL). The system tracks hand movements and classifies signs using motion, trajectory, and hand shape analysis.

Area of Science:

  • Computer Vision
  • Human-Computer Interaction
  • Linguistics

Background:

  • American Sign Language (ASL) is a primary communication method for the deaf community.
  • Automated interpretation of ASL is crucial for enhancing accessibility and communication.
  • Existing methods often struggle with the dynamic and nuanced nature of sign language.

Purpose of the Study:

  • To develop and present an image processing algorithm for interpreting American Sign Language (ASL).
  • To enable automated recognition and classification of ASL signs.
  • To improve the accuracy and efficiency of ASL interpretation systems.

Main Methods:

  • Hand motion detection and tracking using image processing techniques.
  • Classification of signs based on adaptive clustering of stop positions.

Related Experiment Videos

  • Analysis of trajectory shape and hand shape matching at stop positions.

    • Main Results:

    • The algorithm successfully detects hand motion and tracks hand location.
    • Adaptive clustering effectively classifies signs based on movement patterns.
    • Integration of trajectory and hand shape analysis enhances sign interpretation.

    Conclusions:

    • The proposed image processing algorithm offers a viable method for ASL interpretation.
    • The system demonstrates potential for real-time ASL recognition.
    • Further development could lead to improved communication tools for the deaf community.
